Well, I'd take Solaris (1972) over any and all Marvel crap too.

And viewers in general would gain much more subtle understanding of the world, appreciation of art, mature emotions and storytelling, exposure to global cultures (not just heroes-in-spandex-Hollywood-commercial monoculture) and lots of other things besides, if they didn't watch Marvel movies and watch arthouse cinema instead.

Or, as we call it here, just "cinema" (it doesn't need a qualifier, we call the rest "Hollywood crap" instead).
